Question

If f(x) = x - 4, what does f(3) represent?

The value of (x - 4) when x = 3

The value if x when (x - 4) = 3

The value of 3f(x) when x = 3

The value of f(x) when (x - 4) = 3

Answer 1

put x=3

Answer 2

f(3)=3-4=-1
so f(3) represent value of x-3 when x=3

Answer 3

yep just fire it buddy

Answer 8

Brenda deposited some money in a bank. The bank paid her a simple interest every year. After t years, the amount of money f(t), in dollars, that the bank paid Brenda was $2000 greater than 10 times the number of years. Which statement best describes the steps to sketch a graph showing the relationship between f(t) and t?

Label t on the x axis and f(t) on the y axis and plot a graph having slope = 2000 and y intercept = 10.

Label t on the x axis and f(t) on the y axis and plot a graph having slope = 10 and y intercept = 2000.

Label f(t) on the x axis and t on the y axis and plot a graph having slope = 10 and y intercept = 200.

Label f(t) on the x axis and t on the y axis and plot a graph having slope = 2000 and y intercept = 200.

Answer 9

ok
so time on x axis and f(t) on y axis
f(t) = total amount=10t+2000
f(t)=10t+2000

Answer 10

slope =10
and intercept = 2000

Answer 11

option B
